The International Cooperative Alliance defines a cooperative (also known as co-operative, co-op, or coop) as "an autonomous association of persons united voluntarily to meet their common economic, social, and cultural needs and aspirations through a jointly-owned and democratically-controlled ". Cooperatives may include:
Research published by the Worldwatch Institute found that in 2012 approximately one billion people in 96 countries had become members of at least one cooperative. The turnover of the largest three hundred cooperatives in the world reached $2.2 trillion – which, if they were to be a country, it would make them the seventh largest.
One dictionary defines a cooperative as "a jointly owned enterprise engaging in the production or distribution of goods or the supplying of services, operated by its members for their mutual benefit, typically organized by consumers or farmers". Cooperative businesses are typically more economically resilient than many other forms of enterprise, with twice the number of co-operatives (80%) surviving their first five years compared with other business ownership models (41%). Cooperatives frequently have social goals which they aim to accomplish by investing a proportion of trading profits back into their communities. As an example of this, in 2013, retail co-operatives in the UK invested 6.9% of their pre-tax profits in the communities in which they trade as compared with 2.4% for other rival supermarkets.
The International Co-operative Alliance was the first international association formed (1895) by the cooperative movement. It includes the World Council of Credit Unions. A second organization formed later in Germany: the International Raiffeisen Union. In the United States, the National Cooperative Business Association (NCBA) serves as the sector's oldest national membership association. It is dedicated to ensuring that cooperative businesses have the same opportunities as other businesses operating in the country and that consumers have access to cooperatives in the marketplace. A U.S. National Cooperative Bank formed in the 1970s. By 2004 a new association focused on worker co-ops was founded, the United States Federation of Worker Cooperatives.
